HARNESS PAD-PLATE.

SPECIFICATION forming part of Letters Patent No. 249,693, dated November 15,1881.

(No model.)

To all whom it may concern 7 Be it known that I, JOHN THoMAs,ofOedar Rapids,in the county ofLinn and State otIowa, have invented a new Improvement in Harness Pad-Plates; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a perspective view; Fig. 2,an under-side view; Fig. 3, a longitudinal section on the hinging-line; Fig. 4, alongitudinalcentral section; Fig. 5, an under-side view with. the covering-plate removed.

This invention relates to an improvement in harness pad-plates, the object being to hinge I the two sides or wings to the central part; and it consists in the construction, as hereinafter described, and particularly recited in the claim.

A represents the, central part, constructed with an opening, a, to receive the water-hook, and also the backstrap 100p B. The plate is also constructed with a downwardly-projecting flange, 1), upon each side, and on the under side with lugs d, projecting inward from each flange for a short distance and arranged upon opposite sides of the center.

D D are the wings or side pieces, each constructed with a flange, c, at each side, and at thcirinner ends with trunnions, f, to set over the lugs d on the central plate, A, as seen in Figs..3 and 5; then upon thelugs andover the inner ends of the wings D a covering-plate, 5 E, is arranged, and secured by means of the water-hook F, as seen in Fig. 2, the base of the water-hook resting on the plate A, the shank extending down through the cover E, and there fitted with a nut, h, to bind the parts together. The wings are recessed at each side below the trunnions, forming atongue, t, and so as to permit the play of the two wings, as indicated in broken lines, Fig. 5; but if such plate is not desired the trunnions may lie in close seats, so as to permit simplya hinged or swinging movement of the wings, as indicated in broken lines, Fig. 4. This construction makes a complete metal hinge, simple and durable.

Ido not wish to be understood as broadly 5o claiming the wings of a pad-plate hinged .to the central part, as such, I am aware, is not new.

I claim- As an article of manufacture, the herein-described harness pad-plate, consistingot'the central plate, A, and two metal wings, D D, the wings constructed with trunnions to restin corresponding seats on the under side of the plate A, substantially as described.
